I think it's fair to say that a lot of people prefer practical effects in movies over the easy modern day option of CGI. Most of the time practical effects worked well, but every now and again there are some pretty noticeable fails. Other times of course, there are 'blink and you'll miss it' mistakes in movies. Sometimes the crew members will get in the way, or there will be a shot where we can see a part of the set we aren't supposed to. Either way, here are some of the funniest horror movie mistakes I have personally come across, so check em out and tell me in the comments if you noticed them too!

#1 - The Blob (1988)

When the Blob is 'eating' Paul at the doctors office, his arm is the only part that hasn't been covered in slime. It's more than obvious that there's a big cardboardy looking tube around his arm, and the blob's ooze falls around it.

#2 - Scream 2 (1997)

Just as Cici is thrown off the supposed third floor balcony, a crew members head pops up over the edge! This is a blink and you'll miss it mistake.

#3 - A Nightmare On Elm Street (1984)

When Nancy is running up the stairs away from Freddy, you can VERY obviously see the second pre-cut goop hole on the next step.

#4 - The Shining (1980)

In the opening scene where Jack is driving through the hills to the Overlook, we can see the shadow of the filming helicopter following him.

#5 - Red Dragon (2002)

The film is set in the early 1980's, yet when Will is going through a draw he finds a VHS of 'Mrs Doubtfire' - which wasn't released until 1993.

#6 - Fright Night (1985)

During the finale in the basement, wires can be seen suspending Jerry in the air when he lunges towards Peter, sending him crashing into shelves stacked with glass bottles.

#7 - Halloween (2007)

Lynda calls Laurie from a land line phone in the Myers house. The house had been abandoned for fifteen years and wouldn't have a working phone.

#8 - Wolf Creek (2005)

There is the reflection of one of the crew members in Ben's sunglasses, when he is taping himself at the petrol station.

#9 - The Texas Chainsaw Massacre (1974)

Just after the hitch-hiker smears blood from his hand down the side of the van, the next shot shows the van driving away down the road, and the blood has mysteriously vanished.

#10 - Friday the 13th Part 3 (1982)

Plot hole: Jason somehow manages to get both halves of Andy's body on top of the wooden ceiling rafter, without getting a single drop of blood onto the hammock or floor. Then as soon after Debbie gets into the hammock below, blood starts dripping. Why, and how?
